In all its activities, the Association of Interchurch Families is working to strengthen marriage and family life and to promote Christian unity.

It offers a support network for interchurch families (where the partners belong to different denominations - often a Roman Catholic and a Christian of another communion) - for partners and parents, for growing children and young adults - and an information service to all concerned for their welfare (clergy and ministers, relatives and others).

It gives interchurch families a voice in the churches: this is done by articulating the experience of these families in all their diversity; by focusing attention on interchurch couples' need for pastoral care which takes seriously both their marriage commitment to one another and the fact that two churches are represented in their family; by affirming at local, national and global level the gifts of interchurch families and their potential as a catalyst for wider church unity.
